摘要
本文基于2005-2018年中国省级面板数据,构建时变面板平滑转换回归模型,实证检验渠道势力对农产品市场价格波动的非线性影响效应。研究发现:渠道势力对农产品市场价格波动存在显著的非线性影响,且批零相对规模势力门限变量下的非线性效果更加强烈。批零相对规模势力低于门限变量2.264时,渠道势力对农产品市场价格波动发挥平抑效应,之后随批零相对规模势力的提高,农产品市场价格波动加剧;批零相对运营势力低于门限变量0.128时,渠道势力加剧农产品市场价格的波动,之后随批零相对运营势力的提高,其对农产品市场价格波动发挥非线性的平抑作用。最后,本文从创新农产品流通模式和提升农产品流通运营水平等方面提出政策建议。
Based on the provincial panel data of China from 2005 to 2018,this paper constructs a time-varying panel smooth transformation regression model to test the non-linear influence mechanism of channel power on the price fluctuation of agricultural products market.It found that channel power has a significant non-linear effect on the price fluctuation of agricultural products market,and the non-linear effect of zero rating is stronger than that of scale power threshold variable.When the relative scale power of wholesale and retail is lower than the threshold variable 2.264,the channel power will play a stabilizing effect on the price fluctuation of agricultural products market;then,with the increase of the relative scale power of wholesale and retail,the price fluctuation of agricultural products market will increase.When the relative operation power of wholesale and retail is lower than the threshold variable of 0.128,the channel power aggravates the fluctuation of the market price of agricultural products.Then,with the increase of the relative operation power of wholesale and retail,it plays a non-linear stabilizing role in the price fluctuation of agricultural products market.Finally,the paper puts forward policy suggestions from the aspects of innovating the circulation mode of agricultural products and improving the circulation and operation level of agricultural products.
